Current issues:
Rocky 8 images are building as rocky 9
Rocky 9 images are failing to boot due to to an issue with cloud-init config not being parseable:

[   12.623671] cloud-init[966]: 2024-03-27 09:48:06,919 - util.py[WARNING]: Failed loading yaml blob. Invalid format at line 102 column 5: "while parsing a block mapping

I think that issue is caused by a whitespace error on this line of the containerfile
A fix is in progress
